Printout has Black Vertical Lines
this is what you would do, if your print out has black vertical lines on copies, send faxes, and scans. open the scanner document feeder lid, there's a big square glass panel on the right, and smaller glass strip on the left. clean both these glass part with some tissue, or kithen towel with glass cleaner if you have it. if you do not have glass cleaner, then try a simple mix of water or alcohol will do. do not apply cleaner directly on to the glass. make sure that all spots have been removed. after cleaning, wipe dry with some more tissue or kitchen towel. now close the document feeder lid. now test the print quality by copying a document using the ADF, to ensure there are no lines or spots appearing on the copy. and that's it! thanks for watching bye!
